New high-rises, green space, and retail are underway in St. Petersburg’s Carillon Office Park for the master-planned Echelon City Center development.

Echelon City Center, first announced in the early 2000s, is a 20.5-acre mixed-use project being developed by Echelon, a St. Petersburg-based real estate company.

The vision of Echelon City Center is similar to Midtown, an urban neighborhood between Tampa's Westshore and Downtown districts, anchored by a Whole Foods Market and features retailers such as REI.
